似乎我的某个内核被删除了。也许这就是我遇到这个错误的原因。我该怎么修复它?我能重新安装什么东西(也许是 基础环境 中的内核)吗?
如果没有更好的选择,我会尝试重新安装Anaconda作为最后的手段,具体方法请参考: Jupyter笔记本中的默认内核(Python3)不起作用。 我已经尝试使用以下方法:
输出:
但我必须有另一个内核(我想可能是某种方式被删除了)与我的基本环境相关联。

如果没有更好的选择,我会尝试重新安装Anaconda作为最后的手段,具体方法请参考: Jupyter笔记本中的默认内核(Python3)不起作用。 我已经尝试使用以下方法:
- 安装Jupyter Lab:
要求已满足
- 运行“jupyter lab”时内核不显示
- UI显示“无内核”,但我明确有一个
- 在Python3中运行Jupyter Notebook时出现内核错误

当前内核列表
jupyter kernelspec list
输出:
Available kernels:
python3 C:\Users\raysu\AppData\Roaming\jupyter\kernels\python3
vpython C:\ProgramData\jupyter\kernels\vpython
但我必须有另一个内核(我想可能是某种方式被删除了)与我的基本环境相关联。
